7x - 4y + 8=0 slope intercept is y=mx+b so you have to get y alone
+4y =+4y so add for y on both sides
7x + 8=4y Then divided 4y on both sides
7x/4 8/4= 4y/4
slope intercept form is y=7/4x+2
Z-scores (left tail) of a given variable X are calculated by
Z(x)=(x-mean)/standard deviation.
For Mary:
Zm(124)=(124-110)/8=14/8=1.75
For Carrie:
Zc(289)=(289-250)/20=39/20=1.95
therefore
Zc>Zm
Answer:
C
Step-by-step explanation:
Its C because it doesn't depend on the marbles there to separate picks so neither will affect each other
Answer:
The mean number of cookies was 33.5
Step-by-step explanation:
Add the values of the terms and divide by the number of terms.
So...
26 + 38 + 45 + 25 = 134
134 ÷ 4 = 33.5
